My calla lilies don’t bloom

They have white on their leaves. They were given to me by a neighbor. I store them under my house, just like she does and bring them out in spring.

This could be powdery mildew from being stored in a damp location.

Treat the plant with Neem Oil.

They also may need more Phosphorous to encourage flowering. Bone Meal is a good way to do so.
